collegekid - Sonata problems

collegekid1

So my 2006 hyundai sonata recently has been having engine problems and i replaced the ecm already and it still acts up it loses power only when i go down hill to fast it just cuts out and will barely move until i park and shut off the car for a couple min then its fine again kinda.
